Hello all,

In device manager I see a lot of COM-ports, I all know where to use them for, but I also see a COM1 port.
My motherboard doesn't have a serial port (RS232) on board, so I am curious what this COM1 port is.

Thank you for your answers

Cheers
Kees

Perhaps it is virtual? A screen shot may be helpful.

A quick glance at your motherboard's manual shows a com port header.

I believe that I've never owned a PC case that had cabling to use such a header.

How to wire the LPT and COM port headers on a motherboard?

I would like to add an LPT and a COM port to my computer. The board has no LPT or COM port on the I/O panel on the back. However, there are LPT and COM port headers on the board. You can see these
superuser.com superuser.com
?
Otherwise, use a USB to serial adapter cable.

Adding COM Ports in Windows 11

To add a COM Port, open Device Manager, select any node in the Device Tree, then select Action from the menu, and pick Add Legacy Hardware.
Follow the instructions to install the device manually.
